How to change CPU Fan Speed without BIOS


Have you ever noticed how your CPU fan is controlled? You need to regulate the CPU fan to solve sudden problems periodically. This issue can be excessive heat and decrease fan speed. For this, the command should be in your control. 

Using bios to regulate the speed makes the task easier. On the other side, using bios to control the fan speed is always problematic. Thus, the essential factor in negotiating is how to change CPU fan speed without BIOS. 

I am here to answer this question. So, let’s jump into the more detailed information! 

How can you alter the fan speed without accessing BIOS?

One of several best methods to modify CPU fan speed is through BIOS. However, BIOS will not always enable you to do so. If you are having trouble controlling your fans without using BIOS, there are two options.

  • Fan Control Software 
  • External Fan Controller 

Let’s talk about these methods in-depth! 

Fan Control Software 

Various fans are controlling available software, including Corsair Link, Note-Book Fan-Control, HW Monitor, Argus Monitor, Speed-Fan, etc. All of them are useful, but I will show you how and when to use Speed-Fan to manage the fan’s speed in this article.

What is a speed fan?

Speed fan is a free program for Microsoft Windows that controls CPU system fan speeds and conditions. It has a primary fan variable speed option and an automatic fan traction control function. It detects the heat of the elements and adjusts the speed accordingly.

Note: 

Speed-Fan is among the most popular fan control programs. Its layout may appear archaic to you, but it is a free program written by a single person. For newcomers, starting up the software can be difficult. Thus, by following the steps given below, you can achieve it!

Stage 1: 

Downloading and Installation of Speed-Fan

First of all, download the Speed-Fan software from this page. Then, install it after it has been downloaded, and then activate it. The program will check all of the ports on your system after you activate it.

Stage 2: 

Set up the Fan Control 

You do not have to modify the fan speed using the PWM controllers as soon as the software is opened. It is necessary to set it up first.

  • A new window will pop up when you click “Settings.”
  • Now select “Advanced.”
  • After selecting” Advanced,” choose the “Chip” option from the menu bar.
  • Search for your PWMs in the menus (if you’re not sure where they are, you have to click on all the chip selection choices.)
  • Choose the PWMs you like to regulate once you have located them.
  • After choosing the PMW, a “Switch to” menu will appear, from which you have to select “Automatic” or “Software-controlled.” 
  • To preserve the changes, make sure you select “Remember it.”
  • Now return to the main window looking for PWM1, PWM2, PWM3, PWM4, and PWM5. 
  • You can now directly enter or use switch keys to alter fan speed by selecting the PWM you selected.

Stage 3 

Build an automatic fan control system

I have shown you how to change Speed-Fan in stage 2, but it’s a manual system. You may also enable automatic fan adjustment. If your CPU continuously gets overheated then the speed-fan system will boost the fan speed and then drop it when it cools down.

By selecting “Settings” and then “Fan control” and checking enhanced fan control, you may set up automated fan control. Thus, it’s a bit complex task to do.

External Fan Controller 

If all else failed and you are at a loss for what to do, use an additional fan controller. It is manually operated and enables you to track and modify the fan speeds on your computer.

Corsair Commander Pro, Thermaltake Commander, and Noctua are three of the best in the industry. Invest wisely in this choice. 

You will require high-quality, dependable fan controls for the most outstanding results. It will help to maintain a balance between CPU temperature and fan speed.

Also, be sure to purchase a fan regulator that is precise and helpful. For this, you have to consider the appropriate appearance, pin connections, settings, and ports. Thus, a wise investment pays off in the long run.

Is it hard to change the CPU fan speed without BIOS? 

Yes, it is a slightly tricky method. If you don’t have any other options, the most straightforward solution is to purchase an external fan controller. The fan controller is simple to locate and use, as well as novice-friendly. 

If you are still having trouble controlling the fan, get professional assistance. 

Conclusion 

Well, all that I have covered in this article goes towards the answer to how to change CPU fan speed without BIOS. By reading this article, you can easily decide how you can obtain the solution.

If you find the installation and use of the Speed-Fan program to be difficult, you can purchase an alternative fan controller and use it instead
